Description

Technical Field

[0001] This utility model relates to the field of pipette technology, specifically to a pipette holder. Background Technology

[0002] A pipette is a laboratory tool used for the precise measurement and transfer of small volumes of liquid. It is widely used in fields such as biology and chemistry. It can transfer liquid from one container to another within a certain range and is one of the most commonly used pieces of equipment in the laboratory. As a precision instrument, pipettes should not be bumped or knocked during use and storage. Even slight impacts may affect the accuracy of the pipette. Therefore, pipettes need to be handled and used with care. In order to quickly change pipettes of different sizes, a rack is usually installed on the work surface during use.

[0003] However, the placement racks are generally exposed structures, leaving pipettes directly exposed to the air. Over time, dust can easily accumulate on the pipettes, causing contamination during subsequent use and seriously affecting normal use. Moreover, the pipettes are placed directly on the placement rack without protection, making them prone to falling off or even being damaged due to collisions. Therefore, improvements are urgently needed. Utility Model Content

The lower positioning frame 10 is fixed to the outer wall of the bottom of the holder body 1, and the interior of the lower positioning frame 10 is provided with equally spaced lower placement grooves 11. The upper placement grooves 3 and the lower placement grooves 11 are provided with pipette bodies 4.

[0027] The upper protective cover 8 is fitted on the upper part of the pipette body 4, and the lower protective cover 9 is fitted on the lower part of the pipette body 4. A groove 16 is provided on the outer wall of the placement rack body 1 at the position of the pipette body 4, and a movable seat 18 is provided inside the groove 16. A first small cylinder 21 is installed on the outer walls on both sides of the movable seat 18, and a clamping arm 19 is fixed at the output end of the first small cylinder 21.

[0028] Specifically, the pipette body 4 is placed in the upper placement groove 3 and lower placement groove 11 on the surfaces of the upper positioning frame 2 and the lower positioning frame 10. The first small cylinder 21 drives the clamping arm 19 to clamp the pipette body 4, making the placement stable. The anti-slip plate 20 is made of rubber, which increases the friction on the surface of the clamping arm 19 and prevents the pipette body 4 from slipping.

[0032] An upper movable arm 14 is fitted on the outer wall of the double-acting screw 6, and the upper movable arm 14 is threadedly connected to the double-acting screw 6, and one end of the upper movable arm 14 is fixedly connected to the upper protective cover 8.

[0033] A lower movable arm 15 is fitted on the outer wall of the bidirectional lead screw 6 below the upper movable arm 14, and the lower movable arm 15 is threadedly connected to the bidirectional lead screw 6, and one end of the lower movable arm 15 is fixedly connected to the lower protective cover 9.

[0034] A small motor 7 is installed at the top of the main body 1 of the placement rack at the position of the bidirectional lead screw 6, and the output end of the small motor 7 extends into the interior of the drive groove 5 and is fixedly connected to the top of the bidirectional lead screw 6.

[0035] Specifically, the small motor 7 drives the bidirectional lead screw 6 to rotate, so that the upper movable arm 14 and the lower movable arm 15 drive the upper protective cover 8 and the lower protective cover 9 to move towards each other until they close. The ends of the upper protective cover 8 and the lower protective cover 9 and the side close to the main body 1 of the placement rack are hollow structures, so that the upper protective cover 8 and the lower protective cover 9 form a sealed space after they are closed. The pipette body 4 is inside the upper protective cover 8 and the lower protective cover 9. The upper protective cover 8 and the lower protective cover 9 play a role in dust prevention and protection for the pipette body 4, thereby preventing the pipette body 4 from being contaminated, and at the same time preventing the pipette body 4 from being knocked off or damaged.

[0036] A limiting frame 12 is fixed inside the lower placement slot 11, and the limiting frame 12 has a U-shaped structure;

[0037] A second small cylinder 22 is installed on the top of the groove 16 above the movable seat 18, and the output end of the second small cylinder 22 is fixedly connected to the top of the movable seat 18.

[0038] The first small cylinder 21 and the clamping arm 19 are both provided in two sets and distributed on both sides of the pipette body 4;

[0039] An anti-slip sheet 20 is attached to the outer wall of the clamp arm 19 near the pipette body 4, and the anti-slip sheet 20 is made of rubber.

The first small cylinder 21 drives the clamping arm 19 to clamp the pipette body 4, ensuring stable placement. The anti-slip plate 20 is made of rubber, increasing the friction on the surface of the clamping arm 19 and preventing the pipette body 4 from slipping. The second small cylinder 22 drives the movable seat 18 to slide along the guide rod 17, thereby adjusting the position of the clamping arm 19 and facilitating the adjustment of the position of the pipette body 4. Then, the small motor 7 drives the bidirectional lead screw 6 to rotate, causing the upper movable arm 14 and lower movable arm 15 to drive the upper protective cover 8 and lower protective cover 9 to move towards each other simultaneously until they close. The end of the lower protective cover 9 and the side close to the main body 1 of the placement rack have a hollow structure, so that the upper protective cover 8 and the lower protective cover 9 form a sealed space when they are closed.
